本文重新评估了1988年至1995年期间美国环保署自愿33/50计划在减少17种高优先级有毒化学品排放方面的有效性。相反,以前的研究,使用程序参与信息在公司层面上,并找到混合的证据,该计划的有效性,我们的分析使用的参与状态,在设施层面上,并显示进行分析的重要性,在一个分解的规模。我们发现,减少释放率显着高于计划参与者比nonparticipants,但效果是衰减时,估计使用公司层面的参与数据。(JEL问题51、问题52)
This paper reevaluates the effectiveness of the EPA’s voluntary 33/50 program in reducing the releases of 17 high-priority toxic chemicals for the 1988–1995 period. Contrary to previous studies that use program participation information at the firm level and find mixed evidence on the effectiveness of the program, our analysis uses participation status at the facility level and shows the importance of undertaking analysis at a disaggregated scale. We find the rate of reduction in releases was significantly higher for program participants than nonparticipants, but the effect is attenuated when estimated using firm-level participation data.
